Woman faces fine over jetski death

A 21-YEAR-OLD Australian woman plans to plead no contest to a charge of destroying evidence after her boyfriend killed a teenager in a jet ski accident in Hawaii.

Under a plea by mail submitted to a Honolulu court, Natasha Ryan of Brisbane admitted on Tuesday that she purposely deleted video she had taken of the August 5 jet ski accident.

Kristen Fonseca, 16, of California was killed in the accident. Tyson Dagley, 20, also of Brisbane, was convicted of third-degree negligent homicide.

According to a report in the Honolulu Star Advertiser, a court will decide on an agreement proposed by Ryan's lawyer.

Ryan is on $US500 ($A480) bail and her lawyer is arguing the amount should be forfeited as a fine.

The prosecutor wants a fine of $US2000.

Dagley was standing on a rented jet ski before it hit Fonseca's watercraft from behind. Dagley admitted he was not paying attention to where he was going, only looking at his girlfriend who was taking video and photos.

Dagley was sentenced to the 12 days he had already spent in jail and ordered to pay the Fonseca family $US78,000 in restitution.
